On paper it looks like no one can touch it from a driver perspective (and price). But I can't seem to find anyone who has tried it with Protools yet.
All I am looking for is a stable Thunderbolt interface that does not need a secondary mixer to make it even usable to track live recordings without massive latencies. That runs ProtoolsHD12 software smoothly.
I have tried all the major players, Apogee, UA, Antelope, MOTU and they are utterly useless when not tracking through their own Software Mixers.
Software Mixers is just a solution for writing bad drivers in my opinion.
The only one that seems to be able to do it is the RME UFX+. I have always loved RME for their solid drivers but at the moment they don't have an entry level Thunderbolt interface (sub$1000).
Anyone!?

I just picked up a Quantum 2 interface and I have to say that I'm impressed with the performance of this unit. The driver is very stable, efficient and works very well on my Win 10, PT 2018 system. I can run higher track counts and a lower buffer setting than I can with my Clarett.

I don't have exact latency numbers, but have no issues tracking through plug-ins.

Definitely worth a look if you are in the market for a TB interface at a good price.

Thats good to hear. I will probably pick one up for my portable rig and ditch my Apollo Twin. I have been using a UFX+ with another studio setup and it has been working very solid too. Didn't want to spend that much money on another one for my mobile rig though.

I just picked up a Quantum 2, and I have to say I am impressed. I haven't tried it in Mac yet, but my Windows 10 Bootcamp installation works great. I get better stability at 64 sample buffer than I did at 256 samples with any of my other interfaces. Latency is not noticeable by me, and I have no problem tracking though Amplitube 4 or any other plugin I might need.

Interestingly, I can get the buffer all the way down to 16 samples in the Studio One 3 Artist software that came with the interface. And it seems to be stable at that setting as well. Pro Tools doesn't even see 16 samples as an option, and 32 samples is too taxing on my aging system. But none of that matters since I get acceptable (unnoticeable) latency performance at 64 samples at 44.1 KHz. And I like Pro Tools too much to bother learning another DAW right now.

Update: I tried it on Mac High Sierra, and it's rock solid stable at 32 sample buffer. I played with it for only about half an hour, but it ran perfectly with a few different sessions.

Nice! Presonus seems to have done a great job with the Quantum driver; at least on Windows.
